Search stock photos by color:
A new type of search at IStockPro, where you can search for a stock photo by color. Via Jim Rutherford. If this service is mixed with the technique described in a previous post of mine, Colors in nature and interface design”, (interface skinning by sampling pictures) it would give on-demand themes for user interfaces. More stuff on color over at Sarah Allens blog.
Found color search on http://www.shutterpoint.com too, cool!
